Water-wheel



UNITED STATES PATENT OFFICE.

SAMUEL B. GOFF, OF CAMDEN, NE\V JERSEY.

WATER-WHEEL.

SPECIFICATION forming part of Letters Patent No. 426,265, dated April 22, 1890.

Application filed November 11, 1889. Serial No- 329,902. (N0 model.)

To all whom it may concern.

Be it known that I, SAMUEL B. GOFF, a citizen of the United States, residing in the city and county of Camden, State of New Jersey, have invented a new and useful Improvement in \Vater-Vheels, which improvement is fully set forth in the following specification and accompanying drawings.

My invention relates to a paddle-wheel for steamboats, &c.; and itconsists, first, of a double wheel mounted on a single shaft, an acceleration of speed thereof being caused by exhaust or live steam; next, of the train of gearing used to relatively connect the inner and outer wheels and shaft, and, finally, of the combination of parts, as will be more fully hereinafter set forth.

Figure 1 represents a side elevation of a paddle-wheel embodying my invention. Fig. 2 represents a vertical section thereof. Fig. 3 represents a top plan View, partially broken away, of the wheel on a reduced scale.

Similar letters of reference indicate corresponding parts in the several figures.

Referring to the drawings, A designates a shaft, which may be either loosely mounted or driven by power. On said shaft is fixed an outer wheel B, having peripheral blades C, under which are diagonallyqnounted ducts or boxes D, divided into upper and lower compartments by plates E. A power-generating medium supply pipe or duct F is stationarily secured in position over the inner side of the upper part of wheel B, and a hood orcovering-plate G is mounted over the place of engageinent of the duct F with said wheel for the purpose of permitting the steam, after passing through the above-setforth parts, to exhaust at this point.

On shaft A is rigidly keyed a gear'll, which turns therewith. Over the said shaft is mounted a sleeve J, having end flanges K, to which are attached pinions L, meshing with the gear H and engaging the same diametrically opposite to each other. Over the sleeve J is situated. another sleeve M, having gearteeth N cut in the inner surface of the outer ends thereof, with which mesh the pinions L on said sleeve J, said outer sleeve M. supporting the inner wheel P, the latter being constructed. with inwardly-projecting blades Q.

The sleeve M is preferably provided with the flanges R, bearing on sleeve J and supporting anti-friction rollers S, impinging against the flanges of said sleeve J, to thereby cause an easy movement of the said wheel P.

. Inside of the wheel P is mounted an exhaustpassage T, consisting of a sheet-metal pipe of substantially the form shown, the top portion of which is open to take the motion-generating medium from the paddles of wheel P, and open at the bottom near the water-line to throw the said medium onto the water.

The diagonal arrangement of the ducts or boxes 1) causes thepower applied thereagainst to have greater force over the surface exposed thereto.

Between the duct F and the adjacent side of the wheel a suitable packing will be inserted to prevent escape of the steam and direct the same into the ducts or boxes D.

The blades O of wheel 13 are mounted at an angle to the diametric plane of the wheel. As shown in Fig. 1, said blades 0 present a fiat surface to the water and gradually taper off when passing through the water at the greatest point of resistance, thereby reducing the resistance of the water against the wheel and at the same time allowing said blades to gain sufficient hold to produce propulsion.

In operation steam, water, or air enters the duct F, and passes through the ducts or boxes D of wheel B and advances or starts the revo lution of the wheel entire. If steam or air be used, a part thereof flows up against the paddles O of the said wheel 13 and a part flows down and strikes the paddles or blades Q of the inner wheel P, revolving the latter in a reverse direction to the wheel 13, said steam or air being exhausted through the outlet or exhaust-passage T. When water is used, it will flow into ducts D and down through the same onto the blades Q direct. The outer whee]. B is turned or revolved in the direction of the arrow shown in Fig. 1, and imparts its motion to shaft A. If said shaftA is of itself driven by power, the additional power given to said wheel B acts as an auxiliary to accelerate the speed of said shaft. The power applied to wheel P is transmitted to sleeve M, andfrom said sleeve, through pinions L, is caused to be carried to the shaft A, through the .gear H thereon, thereby further aiding to accelerate the motion of said shaft. The inner wheel P revolves in a reverse direction to the wheel A and independent of the latter, but the gearing set forth finally causes the power to be applied to shaft A in the same direction as the wheel B imparts it to said shaft.

Either live or exhaust steam may be employed as a power medium, and the shaft F may have amotion given it by suitable means or be driven solely by the wheel set forth.

If the wheel be used with a steamboat, the

' exhaust-steam therefrom may be readily confined and employed as a power medium, or in lieu thereof live steam may be used direct from the boiler.

Having thus described my invention, what I claim as'new, and desire to secure by Letters Patent, is-- 1'. In a paddle-wheel, a central. shaft, an inner wheel movably connected to said shaft, an outerwheel surronndingsaid inner wheel and provided with diagonally-arranged ducts or boxes, said wheels being independent of each other, and the gearing connecting said wheels, substantially as described.

2. In a paddle-wheel,ashaft, an outer wheel provided with deflecting steam ducts or passages, an inner wheel, said wheels having independent movements in reverse directions, and gearing for connecting said inner wheel with the shaft 'to produce power thereon in the same direction as that imparted to the within the said outer Wheel, a central shaft to which said outer and inner wheels are secured, a pipe or duct for conveying the powergenerating mechanism to the ducts of the outer wheel, and an exhanst-passage in the interior of said inner wheel, substantially as described.

4. In a paddle-wheel, a shaft having a gear thereon, an outer wheel fixed to said shaft, a sleeve over part of said shaft carrying pinions in mesh with the gear thereon, and an inner wheel secured to a sleeve having gearteeth in the ends thereof meshing with the pin'ions on said former sleeve, substantially as described.

5. In'a paddle-wheel, a central shaft, an outer wheel having ducts divided into two compartments, paddles above said ducts, a power-generating medium, an ingress pipe or duct for said ducts of the outer wheel, the hood or cap over the place of joining of said pipe or duct on the side of the wheel, the inner wheel having blades, as set forth, the exhaust-passage located in said inner wheel, and the gearing connecting the inner wheel with the shaft, substantially as described.
